Compatible Replacement & Equivalent Models
When the AAI135-S00 is discontinued, out of stock, or requires a cost-effective alternative, the following models are commonly evaluated as replacements or equivalents:
- Yokogawa AAI141-S03 — 8-channel AI, 4–20 mA, HART; same CENTUM VP platform, fewer channels
- Yokogawa AAI143-S03 — 16-channel AI, 4–20 mA, HART; direct functional equivalent with updated firmware
- Yokogawa AAI135-S03 — Revised suffix variant; verify firmware and backplane compatibility before substitution
- Yokogawa AAB841-S00 — Analog I/O combination module; suitable when mixed I/O consolidation is required
- Honeywell HC900 AI Module — Cross-brand alternative for migration projects; requires gateway or protocol converter
- Emerson DeltaV AI Card (MD Plus) — Cross-platform alternative; applicable in full DCS migration scenarios
Note: Always verify backplane slot compatibility, firmware version, and system configuration before substituting any module. Contact Konmask for pre-sales compatibility verification.
Why Choose the Original AAI135-S00
- ✅ Native CENTUM VP integration — plug-and-play with no additional configuration

- Not Compatible With: CENTUM XL, CENTUM μXL, ProSafe-RS standalone (without FCS bridge)
Selection Guide
Use the following criteria to determine whether the AAI135-S00 is the right module for your application:
- Channel count needed: If ≤8 channels, consider AAI141-S03 for cost savings; if 16 channels, AAI135-S00 is optimal
- HART requirement: AAI135-S00 supports HART; if HART is not required, AAI135-S00 still applies but non-HART variants may reduce cost
- Platform: Confirm CENTUM VP or CS 3000 — this module is not compatible with CENTUM XL
- Safety requirement: For SIL 2 loops, verify SIL certification documentation with Yokogawa before specifying
- Budget vs. OEM: For budget-sensitive projects, AAI143-S03 (updated variant) may offer equivalent function at lower cost
- Lead time sensitivity: Konmask maintains stock of AAI135-S00 and common equivalents — contact us for availability

Replacement & Compatibility FAQ
Q: Can AAI143-S03 directly replace AAI135-S00?
A: In most CENTUM VP configurations, yes — both are 16-channel 4–20 mA HART AI modules. However, verify the suffix (-S00 vs -S03) against your system’s hardware revision list before substitution.
Q: Is AAI135-S00 compatible with CENTUM CS 3000?
A: Yes, the AAI135-S00 is compatible with both CENTUM VP and CS 3000 FCS platforms using compatible I/O nests.
Q: Can I use a third-party analog input module as a replacement?
A: Third-party modules require a protocol gateway and re-engineering of I/O assignments. This is feasible for full DCS migrations but not recommended for single-module replacements.
Q: What is the lead time for AAI135-S00?
A: Konmask typically ships in-stock units within 3–5 business days. For project quantities, contact us for a dedicated lead time quote.
Q: Do you provide a warranty on surplus/refurbished units?
A: Yes — all units carry a 12-month warranty. Refurbished units are clearly labeled and priced accordingly.
